Malachi 2:9-11

Orthodox Jewish Bible

⁹ Therefore have I also made you contemptible and shefalim before kol HaAm because ye have not been shomrim of darkhei of Me, but have shown partiality in torah.

¹⁰ Have we not all Av Echad? Hath not El Echad created us? Why do we commit chillul Brit Avoteinu by every man breaking faith with his brother?

¹¹ Yehudah hath broken faith, and a toeva (abomination) is committed in Yisroel and in Yerushalayim; for Yehudah hath committed chillul against the Beis Hamikdash Hashem loves, by marrying the bat el nekhar.
